To prevent damage to the electrode, be sure to observe the following cautions for storage.
Store in 40°C maximum ambient temperature and 70°C maximum ambient RH.
For maximum possible shelf life do not disturb polythene sleeve until you are ready to use potentiometers.
Store where there are no harmful gases containing sulphur or chlorine.
